Nike introduced its long-awaited self-lacing shoes on Thursday. The sneakers, called the HyperAdapt 1.0, were introduced at that Nike Innovation 2016 event in New York City by CEO Mike Parker.
The technology has been in the works since 2013 and is based on the Nike Air MAG, a replica of Marty McFly’s sweet sneakers in Back to the Future.
CNN Money reports that Nike senior innovator Tiffany Beers explained that the self-lacing shoes by saying, “When you step in, your heel will hit a sensor and the system will automatically tighten.” After this, the user can press buttons on the side to tighten and loosen the laces to their liking.
The HyperAdapt uses a “more technical, sport version” of the technology the MAG uses. Tiffany Beers added in an interview with The Huffington Post that her team began working on the technology about 10 years ago. Fellow designer Tinker Hatfield was inspired to work on the sneaker when he worked on Back to the Future II in 1989 but had to wait for technology to evolve.
The self-lacing shoes use servo motors, similar to the ones used in small train engines and helicopter wings. The motors sense when a foot is inserted into the shoe and auto-lace the shoes using the small motor. The “brain” measures the pressure until the shoe fits snugly. The motor must be recharged every two weeks.
The Back to the Future replica may only be available for charity auctions this spring to benefit the Michael J. Fox Foundation for Parkinson’s Research. However, the HyperAdapt 1.0 will be available for Nike+ app members by the end of the year.
The HyperAdapt self-lacing shoes will be available in three different colors and should launch for the 2016 holiday season. No retail price has been announced.
